# analyzing-golang-malware-with-ghidra Walks an agent through Go binary analysis in Ghidra: buildinfo, pclntab, function names, dependencies.

Go binaries statically link the runtime, the standard library and every dependency, so you get multi-megabyte files with thousands of functions, and Ghidra handles that poorly on its own. The skill explains where the metadata sits and how to pull it out. Inside are steps for parsing `pclntab` and `moduledata`, locating buildinfo by its magic bytes, and recovering function names from stripped builds. Garble-packed samples go through GoResolver, which computes control-flow graph signatures and matches them against a database of known functions. There is also a pass over embedded module paths and versions, so third-party packages tell you what the sample can do without a full reverse. You need Ghidra 11.0+ with JDK 17+, the GoResolver plugin, the Go Reverse Engineering Tool Kit and Python 3.9+ for the helper scripts. Familiarity with Go runtime internals — goroutines, channels, interfaces — matters here, because the `pclntab` and `itab` steps assume it rather than teach it. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-golang-malware-with-ghidra -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/analyzing-golang-malware-with-ghidra/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/analyzing-golang-malware-with-ghidra/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-golang-malware-with-ghidra -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/analyzing-golang-malware-with-ghidra/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-golang-malware-with-ghidra -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/analyzing-golang-malware-with-ghidra/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install mukul975/Anthropic-Cybersecurity-Skills analyzing-golang-malware-with-ghidra ``` 2. **Manually: put the files in place** - File: `.github/skills/analyzing-golang-malware-with-ghidra/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-golang-malware-with-ghidra -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/mukul975/Anthropic-Cybersecurity-Skills --path skills/analyzing-golang-malware-with-ghidra ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/analyzing-golang-malware-with-ghidra/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-golang-malware-with-ghidra -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mukul975/Anthropic-Cybersecurity-Skills/tree/HEAD/skills/analyzing-golang-malware-with-ghidra/SKILL.md ## When to use it - recover function names from a stripped Go binary - locate buildinfo and identify the Go version used to compile - deobfuscate garble-packed functions via CFG signature matching - list third-party dependencies and module versions - separate Go pointer-length strings from C strings in Ghidra ## Example prompts - analyze this Go binary in Ghidra: find pclntab and pull out function names - this sample is garble-packed — recover the names with GoResolver - extract module paths and dependency versions from the binary ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

Go binaries contain the entire runtime, standard library, and all dependencies statically linked, resulting in large binaries (often 5-15MB) with thousands of functions. Ghidra struggles with Go-specific string formats (non-null-terminated), stripped function names, and goroutine concurrency patterns. Specialized tools like GoResolver (Volexity, 2025) use control-flow graph similarity to automatically deobfuscate and recover function names in stripped or obfuscated Go binaries. ## When to Use - When investigating security incidents that require analyzing golang malware with ghidra - When building detection rules or threat hunting queries for this domain - When SOC analysts need structured procedures for this analysis type - When validating security monitoring coverage for related attack techniques ## Prerequisites - Ghidra 11.0+ with JDK 17+ - GoResolver plugin (for function name recovery) - Go Reverse Engineering Tool Kit (go-re.tk) - Python 3.9+ for helper scripts ``` END THIRD-PARTY FILE 416e12eedb71453c The third-party file has ended.
